Abstract

The present invention relates to a method for manufacturing a particle foam part, in particular a cushioning element for sportswear, such as a shoe sole, or a cushioning element, which has been produced by such a method, in particular a shoe sole. The method for manufacturing a cushioning element for sportswear such as a shoe sole, may comprise the steps of feeding foam particles into a mold cavity of a mold tool, and welding of the foam particles in the mold cavity while applying a predetermined pressure, wherein the foam particles comprise a fraction of at least 10% by weight of recycled, shredded foam particles (regenerated material) and the welding of the foam particles is effected by means of electromagnetic waves.
